Someone educated can correct me but that doesn’t sound accurate. Even if it Trump were to go full hitler (which is dumb for an aspiring autocrat in this day and age) it wouldn’t work like that. They’d denigrate all non whites but have a specific target group that they persecute/kill. The group needs to be specific for fascism so they can have a sacrificial goat to blame everything on.
Oh yeah for sure, that sounds way more likely my reply is more in following with the other posters “Trump will go full Nazi” hypothesis. Just seems like fascism has a specific way of working that’s more complex than “kill every out group”.
